    I know where the battery is located, but where do I find a replacement? I have 2 Acer's; one battery is dead, the other is OK. pchub.com lists it with a photo, but not in stock. Their photo URL:

Here is how I replaced it.
CMOS battery is under computer battery. Take computer battery out, open the cover under it you will see the CMOS battery is in black plastive cover. Cut a line through the cover until you can reveal soldering point. Use a soldering gun to remove the old one and solder the new one in. Wrap up the cover. You can buy sodering gun for 14 quit. I would not choose the risk to break the computer plus hours to disassemble & reassemble the computer. Note: Time is money! The time I spent is 3 minutes.

    Son Vu is absolutely right. Lift out the main battery, lift up the black plastic cover in the battery compartment and the cmos battery is there wrapped in a black plastic insulating cover. On my Travelmate it is a Maxell 2032 rechargeable battery. It just requires a soldering iron to remove the wires off the old battery and to then connect up the new battery. Seemples see!

Job is complete.

I have done the replacements on both Acers generally using Timo's technique. The first took about 45 mins and the second took less than 30 minutes because I quickly learned the way of lifting the case just enough (it will flex) to pull the connector through to the main battery compartment, then using a stiffer wire, like a paper clip, to push and nudge the new connector back through. I then arranged its wiring layout and plugged it in. I thought if I got into a lot of work doing this, I considered just cutting the wire near the old battery and patching in the new one, which might be like Son9 suggested, but it didn't turn out to be hard at all to fully replace them.
Thanks to all for helping.

A real nightmare: I suppose, C112 and C110 are very similar: It's located left from the touch panel BELOW the plasic - without any opening possibility, probably for security reasons (bios password reset etc.). To access it, you have nearly to put your notebook in parts completely. I recently did that, because I had a broken heat connection between cpu and heatsink.
IF you want to do it, be aware to spend hours... Unplug all removable parts (battery, harddrive, ...). Now loose all screws accessable from below - some are well hidden. Three of them hold the keyboard. Take care not to damage the flat keyboard connector cable, loose it from it's fitting on the MB and put it away. If you look on the lower middel part of the MB now, you see two white plugs connected to the MB. The left one is leads to the battery. If you unscrew all screws below, you COULD try to lift up the plastic topcase a little bit and look under it through the **** - I am not sure, if this is possible... You see the battery in a black or blue coated shrinked plastic cover then, hopefully. If you cannot open the cover wide enough, you maybe even have to uninstall the complete display (4 screes around the rotation foot of the display mount, then remove the top cover completely.

I of course want to point out, that this is a BIG task and you should not try it, if you have not much experience with putting things in parts and reassamble it again ;) No guarentee on my howto posted here, but good luck!

Hello,

who told you that the fault was from the Cmos battery? This is a display issue and not cmos battery. Who ever told you it was a cmos battery problem was wrong. The function of the cmos battery does not concern video problem.

Since the fault has to do with video, you will have to check the screen and screen inverter.

Also, does you tablet PC has a space for any external display like motherboard? You can connect it to an external display to see if there will be a display. ( This is optional, if it does not have external display connector, then you cannot do this).

So review the inverter because there is every possibility that the fault is from there.

I hope this makes sense to you.

Good luck.

How do i change the cmos battery in a travelmate c110. The time and date and bios settings keep changing. Figure it needs a cmos battery. thanks


The cmos battery is exactly located beneath in between the touchpad and speaker, it's a meticulous job, you could see a twin cable leading through the keyboard area. After removing the keyboard, cut the battery wires at the edge of the old battery and replace the new sealed pack by soldering its wires to the same connection. Be cautioned not to break off the slim edges of the keyboard sides by attempting to reach the battery while lifting up top silver panel from the front near the Infrared.

When i turn on my pc it ask for a password i never created, how do i fix this problem


Hello again sounds like it has lost its bios configuration and wants the CMOS re-setting check the hard drive hasn't come loose or your CD if it is an interchangeable one .. and if the floppy drive was in the machine ( not a disk an actual changeable drive ) .was in the last time you shut it down put it back in and reboot see if it's ok unlikely but worth a try
So if no joy you will need to remove the CMOS battery probably located under the keyboard .. or sometimes behind the ram module underneath and a few machines have their own battery holder under the machine .. its silver looks like a large watch battery and is in a plastic holder .. don't touch it with your hands they are static sensitive as are the other components around it .. wear a pair of marigolds the rubber will help protect the circuit ... hope this is a success for you good luck ..

Cmos battery for C110 TCI


The CMOS Battery is behinf the main battery behind a platic shield. The shield is relitivly fragile and glued around the edges. Care should be used removing it to prevent ripping. The battery itself is 3" flat pack glued to the case. Mine was wrapped in a black heat shrink with two wires exiting.
The connector is under the keyboard. You will need to remove the 6 scres from the bottom of the case to release and remove the keyboard. The keyboard ribbon cable is attached through a ZIF socket. Be sure and release the cable before removimng the keyboard. Youll have to trace the CMOS battery leads to determine the correct connector.
I found a Maxell ML2032 rechargable battery. Unfotunatly all the 3" flat pack batteries I have found are LITHIUM ION and not rechargeable. If I find a replacement I will post the information.

This is likely your CMOS battery dying on you and resetting your computer's date. Hitting F2 I belive it is will allow you to access your bios and on the second page you can see your date. It will likely be Jan 1st, 1988. Use your number keys to adjust the date and use your tab key to move between month, day, year, ect.

This is a temporary fix however and you will have to do this often until you have your CMOS battery replaced. I have a Travelmate that has the same problem.
